Ceiling supported systems are available for
diameters 10”-16".
1. Place Appliance: Position the appliance
according to the manufacturer’s instructions.
The flue outlet collar should be placed
between the rafters or joists above, if possible.
2. Frame Support Opening: Drop a plumb
bob to the center of the appliance’s flue outlet
and mark this center point on the ceiling. Refer
to Table 2 for specific framing and clearance
dimensions. Mark appropriate cutting lines
around the center point. Cut a square hole in
the ceiling for the Support Box. Frame a level,
square opening centered over the hole which
you have cut. (Figures 3 and 4).
